Which of the following reactions had the greatest percent yield?

A. Theoretical yield: 52.3 g; Actual yield: 50.7 g
B. Theoretical yield: 17.1 g; Actual yield: 15.7 g
C. Theoretical yield: 38.8 g; Actual yield: 36.2 g
D. Theoretical yield: 24.6 g; Actual yield: 22.5 g

Answer :

Answer:

Option A

Explanation:

As we know

Percent yield is the ratio of actual yield/theoretical yield

a) Percent yield - Theoretical yield 52.3 g; actual yield 50.7g = 0.97 = 97%

b) Percent Yield - Theoretical yield 17.1 g; actual yield 15.7g = 92%

c) Percent Yield - Theoretical yield 38.8 g; actual yield 36.2 g = 93%

d) Percent Yield - Theoretical yield 24.6 g; actual yield 22.5 g = 91%

Hence option A is correct

Final answer:

The reaction with the greatest percent yield is a, with a percent yield of 97.11%.

Explanation:

The percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying by 100. Let's calculate the percent yield for each reaction:

a. Percent yield = (50.7g / 52.3g) * 100 = 97.11%

b. Percent yield = (15.7g / 17.1g) * 100 = 91.81%

c. Percent yield = (36.2g / 38.8g) * 100 = 93.3%

d. Percent yield = (22.5g / 24.6g) * 100 = 91.46%

Based on these calculations, the reaction with the highest percent yield is a with a percent yield of 97.11%.
